Abstract
A driving gear, especially a worm gear, includes a drive shaft, an output shaft, a gear housing, a rotating magnetic pole mounted on one of the two shafts, a Hall sensor resting on the gear housing and mounted in the area of the rotating magnetic pole for detecting the rotation of the rotating magnetic pole or the corresponding shaft, and a gear housing cover. The Hall sensor is mounted on a plate that can be inserted in the housing.
Claims15
